Specification of Letters'Patent.

Patented Feb. 13, 1912.

Application filed October 30, 1911. Serial No. 657,668.

To all whom, it may concern:

Be it known that I, HENRY GEBHART, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Indicators forStreet-Oars; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a 'part of this specification.

This invention relates to new and useful improvements in indicators forstreet cars, to show the streets or stations to those entering cars.

The object of the invention is to provide a device of this characterwhich is simple in construction and efficient in operation, as will bemore fully described in the following specification and particularlypointed out in the claim.

Referring to the accompanying drawings: Figure 1 is a front elevation ofthe indicator with the casing shown in section: Fig. 2 is a verticallongitudinal section on the line aa of Fig. 3. Fig. 3 is an endelevation of the casing; Fig. 4 is a section on the line .7)b of Fig. 2,and Fig. 5 is a view showing a modified form of bearing.

Referring more particularly to the drawings, 1 represents the front ofthe indicator casing, which may be a portion of the car construction.The said casing front is provided with an opening 3 which receives aglass closure 4, through which the indications are observed. Extendingrearwardly from said casing front are brackets 5. As shown in Fig. 5 thebearings 5 may be made in two portions, one of which, to-wit 26, isconnected by a hinge 27, and has a clamping screw 28. This constructionof the bearings enables the changing of indicators when a car is changedto different routes or is operated on difierent lines. The brackets 5provide bearings for pintles 6 which extend from the end members 7 ofthe revolving indicator cylinder. As shown in the present case, said endmembers are hexagonal, each side affording space for an indication, andthe same are connected by cross bars 8. The said cross bars are providedwith inner depressions 9 which form pockets to receive transparentplates 10, preferably made of wheels 14 engaged by rollers 15 mounted ona lever 16 pivoted at 17 and controlled by a spring 18. When theindicator cylinder is rotated, the rollers 15 ride in and out of theserrations, in said wheel, and said spring holds said rollers in saidserrations when any one of the plates is opposite the glass 4, therebypreventing said plates being accidentally rotated.

The plates 10 and the end members 7 are surrounded by a casing 19, oneend of which is provided with indications corresponding to theindications on the plates as will be seen in Fig. 3. These outerindications are for the motorman; to enable him to determine when he hasset the indicator for the public. By means of these indications, and thecrank 13, acting as a pointer, the indication on the plate 10 oppositethe glass 4 may be ascertained by the motorman. To permit theindications to be observed at night, electric lamps 20 are placed in therear of the front or exposed plate 10. The said lamps are attached tothe inner side of hubs 21 of the end members 7. The pintles 6 areprovided with openings 22 for the lead wires 23 of said lamps. Toprevent the side members, and the lamps and plates carried thereby beingcontinuously rotated, and to prevent the wires 23 being broken bytwisting the crank 13 is provided with a projection 24 adapted to engagea web 25 on one of the brackets 5.

Having described my invention I claim:

In an indicator for street cars, the combination with a revolubleindicator consisting of a casing having transparent side plates withindications inscribed thereon, of hollow pintles extending from the endsof said casing, brackets forming bearings for said pintles, one of saidbrackets having a stop thereon, lamps mounted on and fixed to saidcasing, electrical conductors extending from said lamps through saidpintles, and a crank moi nted 011 one of said pintles having a Intestimony WhereofI afiix my signature, pro ect1on thereon adapted toengage the in presence of two witnesses. stop on sald bracket to limitthe rotation of said revoluble member, whereby the elec- HENRY GEBHART.trical conductors are prevented from being WVitnesses:
